NEW COMM SATELLITE – GSFC/KSC @NASAGoddard, @NASAKennedy

“Three, two, one, zero and liftoff of the Atlas five rocket with TDRS-K … broadening, enhancing and improving the capability of space-based tracking.”

The rocket carrying NASA’s new advanced communications satellite, TDRS-K, successfully lifted off Wednesday from the Cape Canaveral Air Force Station in Florida.

“Roll program has begun … rates look good.”

From its geosynchronous orbit, TDRS-K will have a wide enough view of our planet to pick up and relay signals from NASA's fleet of Earth-orbiting spacecraft, including the International Space Station and the Hubble Space Telescope.

TDRS-K is the first of a new generation of comm satellites meant to meet the increased demands of NASA's growing fleet of research satellites.

“Booster has throttled back right on schedule.”

TDRS-K is the 11th satellite in the TDRS series launched by NASA since it began building the space-borne network in 1983. Two additional TDRS spacecraft will follow in 2014 and 2015.

ROBOTIC REFUELING MISSION UPDATE – GSFC

#ISS

The Robotic Refueling Mission wrapped up four of its six-day testing of robotic technology on the International Space Station.

Engineers at Goddard Space Flight Center and operators at the Johnson Space Center successfully maneuvered Dextre, the ISS’s robotic arm, to its target – a fuel valve on a specially-designed practice box. NASA-developed tools precisely cut three separate wires, and removed and safely stowed two unique caps in preparation for the main event – the transfer of simulated fuel. This would be a first-of-its-kind robotic fluid transfer on orbit.

With RRM, NASA is proving technology that will help us understand how we can one day use robots to refuel satellites in space – especially those that were never designed to be serviced. Additional tests of this technology will continue throughout the year.

WORLD’S MOST POWERFUL ENGINE – MSFC

NASA engineers working on the nation’s new Space Launch System have resurrected the world's most powerful rocket engine ever flown -- the mighty F-1 - and test fired its gas generator on the Marshall Space Flight Center’s Test Stand.

What they learn will help engineers develop NASA’s new heavy-lift rocket due to launch Orion and its astronauts into space.

Chris Protz: “If we understand how the gas generator works that was designed in the fifties and sixties, how did it operate, what are the characteristics of that engine, then we have reduced the risks of understanding how can we then bring it into an advanced booster engine.”

The F-1 powered the Saturn V rocket that sent Apollo astronauts to the moon. This 20-second test.is one in a series pushing the F-1 gas generator to limits beyond Apollo-era tests.

MANUFACTURING INNOVATION – MSFC

@NASA_Marshall

President Obama’s proposal for a new National Network for Manufacturing Innovation brought some 350 representatives from industry, academia, and economic development agencies to a NASA co-sponsored workshop in Huntsville.

The “Blueprint for Action” public workshop was a forum at which the network’s proposed design could be reviewed and refined. The Marshall Space Flight Center will be home to one of the network’s regional components, the Institutes for Manufacturing Innovation.

John Vickers, Marshall’s Materials & Processes Laboratory: “Manufacturing innovation and advanced manufacturing technology are critical to NASA. It's critical to all of our missions. It's critical to our science missions. It's critical to our human spaceflight missions, aeronautics missions and our Space Technology Mission Directorate -- technology that we produce.”)

Marshall center director Patrick Scheuermann served as NASA’s representative to the workshop’s Interagency Working Group. NASA’s Space Technology Mission Directorate leads the agency’s participation in the nationwide Advanced Manufacturing network.

HI – C SHOWS SUN BRAIDING – MSFC

A NASA sub-orbital telescope has given scientists the first clear evidence of energy transfer from the sun’s magnetic field to the solar atmosphere or corona. This process, called “solar braiding,” has been theorized yet unobserved by researchers until the High Resolution Coronal Imager, Hi-C, obtained highest resolution images from a large active region in the sun's corona. Launched from the White Sands Missile Range in New Mexico last July, the 464-pound, 10-foot-long Hi-C telescope took 165 images during its roughly 10-minute flight. Initial image sequences were seen to demonstrate the evolution of the magnetic field and its repeated release of energy through activity seen on the sun at temperatures ranging from two million to four million degrees.

NINE YEARS AND COUNTING – JPL

#Opportunity

While the Mars rover, Curiosity, may be grabbing its share of headlines these days, another Red Planet rover is quietly embarking on its tenth year of exploration.

Opportunity is smaller and doesn't carry the same high-tech tools as Curiosity, but since landing on Mars on January 25, 2004, it’s made many notable discoveries -- including the Red Planet’s warmer and wetter past.

Opportunity and its twin, Spirit, were only supposed to explore for three months, but both outlasted their original mission. Spirit lost communication with Earth in 2010 shortly after getting stuck in Martian sand. But Opportunity remains healthy and is studying interesting rocks in a massive crater.

#MRO

Another NASA spacecraft, this one orbiting Mars, is providing new evidence of a wet underground environment that adds to an increasingly complex picture of the planet's early evolution.

Researchers analyzing spectrometer data captured by the Mars Reconnaissance Orbiter (MRO) of the floor of McLaughlin Crater think the 1-point-4 mile deep crater once allowed underground water, which otherwise would have stayed hidden, to flow into the crater's interior.

Layered, flat rocks found at the bottom of the crater contain carbonate and clay minerals that form in the presence of water. McLaughlin also lacks large inflow channels, and small channels originating within the crater wall end near a level that could have marked the surface of a lake.

Launched in 2005, MRO and its six instruments have provided more high-resolution data about the Red Planet than all other Mars orbiters combined.

MONA LISA ORBITING THE MOON – GSFC (CP) Chris Smith Reporting

#LRO

NASA scientists routinely use lasers to track the position of the Lunar Reconnaissance Orbiter's laser altimeter as it orbits the moon. Recently, however, they also tried something a little...different. In addition to tracking the instrument, they used the laser to send a picture of the famous Mona Lisa in the first demonstration of laser communication with a satellite at the moon. To do this, the LRO team used the existing laser tracking signal--sent by the Next Generation Satellite Laser Ranging Station at NASA's Goddard Space Flight Center.

The image was divided into pixels, which were then sent to the spacecraft one at a time by re-timing the regular tracking pulses. By delaying the tracking pulses by specific amounts, LRO scientists could use the difference between the expected arrival time and the actual arrival time to indicate the brightness of an individual pixel. Once the image was sent, scientists corrected for transmission errors caused by the Earth's atmosphere using common techniques used in CDs and DVDs. They also studied signal fluctuations due to Earth's atmosphere. The final image was verified when it was returned to Earth using LRO's radio telemetry system.

This test--and the data obtained from it--sets the stage for future high data-rate laser communication demonstrations that will be a central feature of NASA's next moon mission, the Lunar Atmosphere and Dust Environment Explorer.

So, while lasers are currently being used to track NASA satellites, in the future they may also be used to communicate with them, sending not only data, but perhaps images that one day will be as famous as... the Mona Lisa.

MOVING THE DREAM FORWARD – HQ

#NASA

Charlie Bolden: “I do want to welcome all of you here for what I do hope will be a very inspiring program.”

NASA Administrator Charles Bolden kicked off a special commemoration of the life and vision of Dr. Martin Luther King, Jr. at Headquarters.

The MLK “Day of Remembrance” program featured musical selections, poetry and speakers celebrating the continuing impact of Dr. King’s work and philosophy.

“Tell them about the dream Dr. King, tell them about the dream!!

The NASA Headquarters Chapter of Blacks in Government, BIG, sponsored the event.

NASA ANNIVERSARY: LAUNCH OF APOLLO 14 – January 31, 1971

@NASAhistory

Lift-off, we have lift-off with Apollo 14

Forty-two years ago, on January 31, 1971, the Apollo 14 mission began with the launch of a Saturn V rocket from the Kennedy Space Center. Astronauts Alan Shepard, Stuart Roosa, and Edgar Mitchell manned NASA’s third mission to land on the moon.

“It looks you are about on the bottom step and on the surface, not bad for an old man.”

Shepard and Mitchell conducted two lunar EVAs and collected more material and scientific data than Apollo 11 and 12 combined. And famously, Commander Shepard swung the first golf club in space, sending two balls across the lunar frontier.

“Miles, miles and miles.”

Apollo 14 touched down safely in the Pacific Ocean on February 9, 1971.

NASA ANNIVERSARY: SPACE STATION INTERGOVERNMENTAL AGREEMENT SIGNED – January 29, 1998

@NASAhistory

This commemorative plaque was issued to the United States and the governments of fourteen other countries to mark the signing of the Space Station Intergovernmental Agreement 15 years ago on January 29, 1998. The IGA is an element of the legal structure used to regulate the International Space Station and is an agreement between NASA, The Canadian Space Agency, The Japan Aerospace Exploration Agency, The Russian Federal Space Agency and eleven member states of the European Space Agency.

THE QUESTION: WHO IS KRISTIN MORGAN? - MSFC

Alright, here’s your clue: She won more than $69,000 this month on the nationally-syndicated TV game show, Jeopardy! The answer, posed in the form of a question: Who is Kristin Morgan? The engineer-turned-strategic analyst at the Marshall Space Flight Center leveraged her strong engineering and science background -- and several early college semesters as an art history major – to cash in on the show she’s watched regularly since childhood.

”Who is Richard the Third?”

Morgan thanked her colleagues in Marshall's Office of Strategic Analysis & Communications who pitched in after-hours to help prepare her.

“She has a very impressive five day total of Sixty-Nine thousand, ninety-eight dollars!” $69,089.

Morgan was top money-winner on five Jeopardy! episodes, qualifying her for the show’s next Tournament of Champions!

And that’s This Week @NASA.
